Definitions

  • the present invention relates to an all-solid-state secondary battery.
  • electrode materials interposed between a positive electrode current collector and a negative electrode current collector is pressure-molded in order to reduce the grain boundary resistance of an electrode material consisting of particulate matters.
  • a sulfide inorganic solid electrolyte used as an electrode material particularly has high binding strength and ductility and thus the pressure molding improves adhesion between particles in the electrode material. Moreover, a sulfide inorganic solid electrolyte has lower ionic conductance than an oxide inorganic solid electrolyte and thus the pressure molding is important. Furthermore, the positive electrode current collector and the negative electrode current collector are made of high adhesive materials, thereby reducing an electric resistance between the positive electrode current collector and the negative electrode current collector and the electrode material.
  • the all-solid-state lithium ion secondary battery in which a sulfide inorganic solid electrolyte is used as an electrode material, is however warped to the positive side or the negative side by the pressure molding. If the all-solid-state lithium ion secondary battery has a small maximum outside dimension, the amount of curving is negligibly small, and therefore may not be a problem, whereas if the all-solid-state lithium ion secondary battery has a large maximum outside dimension, the amount of curving is disadvantageously large, and therefore may be a problem. Correcting such a warp may crack the electrode material.
  • An all-solid-state lithium ion secondary battery for preventing such a warp is proposed, in which a positive-electrode active material layer, a solid electrolyte layer, a negative-electrode active material layer, and a negative electrode current collector are stacked on each side of a positive electrode current collector (for example, Patent Literature 1).
  • JP 2009 289534 A relates to an electrode for an all-solid lithium battery.
  • Patent Literature 1 Japanese Patent Laid-Open No. 2001-126756
  • an all-solid-state secondary battery is a single cell battery, the manufacturing process can be advantageously shortened with simple wiring.
  • the all-solid-state lithium ion secondary battery of Patent Literature 1 has a multilayer cell. In other words, unfortunately, the all-solid-state lithium ion secondary battery cannot be a single-cell battery.
  • An object of the present invention is to provide a single-cell all-solid-state secondary battery capable of suppressing warping.
  • an all-solid-state secondary battery according to the present invention is defined in claim 1.
  • the all-solid-state secondary battery allows a warp of the positive electrode current collector and the positive electrode layer and a warp of the negative electrode current collector and the negative electrode layer to cancel each other in a single cell, thereby suppressing warping even in a single cell.
  • an all-solid-state secondary battery according to an embodiment of the present invention will be described below in accordance with the accompanying drawings.
  • the all-solid-state secondary battery is exemplified by an all-solid-state secondary battery containing a solid electrolyte having lithium ion conductivity, that is, an all-solid-state lithium ion secondary battery.
  • the all-solid-state lithium ion secondary battery includes a lithium-ion-conductivity solid electrolyte layer (which, hereinafter, will be simply referred to as a solid electrolyte layer 3) disposed (stacked) between a positive electrode layer 2 and a negative electrode layer 4.
  • a positive electrode current collector 1 is disposed (stacked) on the opposite surface of the positive electrode layer 2 from the solid electrolyte layer 3 while a negative electrode current collector 5 is disposed (stacked) on the opposite surface of the negative electrode layer 4 from the solid electrolyte layer 3.
  • the positive electrode layer 2 and the negative electrode layer 4 naturally act as electrodes, that is, electrode layers.
  • the positive electrode layer 2 and the negative electrode layer 4 both contain a sulfide inorganic solid electrolyte, which will be specifically described later.
  • the positive electrode layer 2, the solid electrolyte layer 3, and the negative electrode layer 4 are all made of powder materials.
  • An insulating film 6 may be disposed around the circumference of the positive electrode layer 2.
  • the positive electrode layer 2 disposed on the surface of the positive electrode current collector 1 is pressure-molded.
  • the positive electrode layer 2 tends to be compressed in the thickness (stacking) direction and to expand in the width direction but cannot be expanded in the width direction because of a friction force F applied opposite to the width direction from the positive electrode current collector 1.
  • This generates a residual stress for expansion in the width direction on the positive electrode layer 2, but as shown in FIG. 4 , the pressure-molded positive electrode layer 2 becomes free of the residual stress so as to tend to be expanded in the width direction.
  • the peel strength of the positive electrode current collector 1 relative to the sulfide inorganic solid electrolyte in a 90° peel test is smaller than 0.2 N/mm, adhesion is low between the positive electrode current collector 1 and the positive electrode layer 2 (containing the sulfide inorganic solid electrolyte). In this case, as shown in FIG. 5 , the positive electrode layer 2 expanding so as to slide on the surface of the positive electrode current collector 1 does not affect the shape of the positive electrode current collector 1.
  • the peel strength of the positive electrode current collector 1 relative to the sulfide inorganic solid electrolyte in a 90° peel test is not smaller than 0.2 N/mm, adhesion is high between the positive electrode current collector 1 and the positive electrode layer 2.
  • the positive electrode layer 2 expands while digging into the surface of the positive electrode current collector 1. This causes a warp of the positive electrode current collector 1.
  • a warp of the positive electrode current collector 1 and the positive electrode layer 2 and a warp of the negative electrode current collector 5 and the negative electrode layer 4 cancel each other so as to suppress warping of the overall all-solid-state lithium ion secondary battery.
  • the positive electrode layer 2 contains a mixture of a positive-electrode active material and a lithium-ion-conductivity solid electrolyte.
  • the weight ratio between the positive-electrode active material and the lithium-ion-conductivity solid electrolyte in the mixture is, for example, 7:3.
  • the positive-electrode active material is an ordinary material used in the battery field, for example, lithium-nickel complex oxide (LiNi x M 1-x O 2 ; M is at least one element selected from Co, Al, Mn, V, Cr, Mg, Ca, Ti, Zr, Nb, Mo, and W), lithium cobaltate (LiCoO 2 ), lithium nickelate (LiNiO 2 ), or lithium manganate (LiMnO 2 ).
  • lithium-nickel complex oxide LiNi x M 1-x O 2
  • M is at least one element selected from Co, Al, Mn, V, Cr, Mg, Ca, Ti, Zr, Nb, Mo, and W
  • LiCoO 2 lithium cobaltate
  • LiNiO 2 lithium nickelate
  • LiMnO 2 lithium manganate
  • the negative electrode layer 4 contains a mixture of a negative-electrode active material and a lithium-ion-conductivity solid electrolyte.
  • the weight ratio between the negative-electrode active material and the lithium-ion-conductivity solid electrolyte in the mixture is, for example, 6:4.
  • the negative-electrode active material is an ordinary powder or foil material used in the battery field, for example, a carbon material such as natural graphite, artificial graphite, graphite carbon fibers, and resin baked carbon, silicon, tin, lithium, oxide, sulfide, nitrides or an alloy regardless of the shape of the material.
  • the lithium-ion-conductivity solid electrolyte for the positive electrode layer 2, the solid electrolyte layer 3, and the negative electrode layer 4 is, for example, an organic compound, an inorganic compound, a material containing organic and inorganic compounds, or an ordinary material used in the field of lithium ion batteries.
  • sulfides such as Li 2 S-P 2 S 5 of inorganic compounds have higher ionic conductance than other inorganic compounds.
  • the positive electrode current collector 1 and the negative electrode current collector 5 are made of materials such as tin on an untreated surface, etched aluminum ( FIG. 8 ) on a surface where multiple spongiform pores are formed by etching, and roughened copper on a surface where multiple low pyramids are formed ( FIG. 9 ). These materials are shaped like a plate, foil, a film, or a metal foil composite.
  • the metal foil composite is a composite which is coated metallic foil, for example, stainless foil coated with carbon.
  • the positive electrode current collector 1 and the negative electrode current collector 5 may be made of the same material or different materials.
  • the positive electrode current collector 1 and the negative electrode current collector 5 achieve a high peel strength (at least 0.2 N/mm) relative to the sulfide inorganic solid electrolyte in a 90° peel test.
  • the current collector 1 or 5 (positive electrode current collector 1 or negative electrode current collector 5) with a size of 50 mm (width direction) ⁇ 100 mm (longitudinal direction) had an Li 2 S-P 2 S 5 layer L of 14 mg/cm 2 with an even thickness formed.
  • the thus obtained collector was pressed into a test piece with 300 MPa in the thickness (stacking) direction.
  • test piece included the Li 2 S-P 2 S 5 layer L (not made of the same material as the positive electrode layer 2 or the negative electrode layer 4) in the peel test will be discussed below.
  • an electrode composite material Pressure molding on the same material (hereinafter, will be referred to as an electrode composite material) as the positive electrode layer 2 or the negative electrode layer 4 reduces binding strength among fine particles.
  • the binding strength is smaller than adhesion between the layer made of the electrode composite material and the current collector 1 or 5.
  • the layer made of the electrode composite material is broken (may be called delamination) in a peel test. This does not cause peeling between the layer made of the electrode composite material and the current collector 1 or 5.
  • a value measured by the peel test is not a peel strength between the layer made of the electrode composite material and the current collector 1 or 5 but a delamination strength of layer made of the electrode composite material.
  • the peel test is to be precisely called a 90° peel test and thus the layer is peeled in the thickness (stacking) direction.
  • the test piece includes the layer made of the electrode composite material
  • the layer made of the electrode composite material undergoes delamination in a peel test.
  • the actual all-solid-state lithium ion secondary battery tends to expand in the width direction instead of the thickness (stacking) direction, thereby preventing delamination of an electrode material.
  • the current collector 1 or 5 is bonded with equal adhesion to any one of the layer made of the electrode composite material and the Li 2 S-P 2 S 5 layer L.
  • One end of the Li 2 S-P 2 S 5 layer L (in the longitudinal direction) of the test piece is fixed to a testing stand B with adhesive A while the other end of the test piece (in the longitudinal direction) is pulled by a chuck C.
  • the pulling direction of the chuck C is always orthogonal to the surface of the testing stand B.
  • the Li 2 S-P 2 S 5 layer L with one end fixed to the testing stand B and the other end pulled by the chuck C is broken sometime.
  • the Li 2 S-P 2 S 5 layer L fixed to the testing stand B and the current collector 1 or 5 start peeling off from each other.
  • a load is measured by the chuck C.
  • the completion of peeling as shown in FIG. 12 , the measurement is also completed.
  • the mean value of loads thus obtained by the measurement is divided by the widthwise length of the test piece to determine the peel strength of a 90° peel test.
  • the positive electrode layer 2 is formed on the surface of the positive electrode current collector 1 by a dry deposition method.
  • the solid electrolyte layer 3 is formed on the opposite surface of the positive electrode layer 2 from the positive electrode current collector 1 by the dry deposition method.
  • the negative electrode layer 4 is formed on the opposite surface of the solid electrolyte layer 3 from the positive electrode layer 2 by the dry deposition method.
  • the negative electrode current collector 5 is then stacked on the opposite surface of the negative electrode layer 4 from the solid electrolyte layer 3.
  • a pressure is applied from the positive electrode current collector 1 and the negative electrode current collector 5 in the thickness (stacking) direction so as to apply a pressure of 98kN/cm 2 (10 tf/cm 2 , 980 MPa) to the positive electrode layer 2.
  • the all-solid-state lithium ion secondary battery is thus fabricated.
  • the all-solid-state lithium ion secondary battery allows a warp of the positive electrode current collector 1 and the positive electrode layer 2 and a warp of the negative electrode current collector 5 and the negative electrode layer 4 to cancel each other in a single cell, thereby suppressing warping even in a single cell.
  • the positive electrode current collector was made of etched aluminum (high adhesion) while the negative electrode current collector was made of electrolytic copper foil (low adhesion).
  • the amount of curving caused by warping was 15 to 20 mm ( FIG. 13 ).
  • the positive electrode current collector was made of stainless foil (low adhesion) while the negative electrode current collector was made of roughened copper (high adhesion).
  • the same amount of curving was caused by warping as in comparative example 1.
  • the positive electrode current collector 1 was made of etched aluminum (high adhesion) while the negative electrode current collector was made of roughened copper (high adhesion).
  • the amount of curving caused by warping could be suppressed to 5 to 6 mm, which is one third that of the comparative example ( FIG. 14 ).
  • the positive electrode current collector 1 was made of tin (high adhesion) while the negative electrode current collector 5 was made of roughened copper (high adhesion).
